Iii-Y the` drawings Figure l'fs'. sde'leietqn 0f a Constructionembodying our invention;

Figure 2 is a top plan view thereof;

Figure 3 is an end view thereof partly in section;

Figure 4 is a cross section on the line 4-4 ofkFigure 1;

Figure 5 is a side elevation, partly Vin section, of a modiedconstruction.

1 are the side frames of the crane carriage and 2 is the crossconnection therebetween. This cross connection is the trolley track andis preferably an I-beam upon the lower anges of which the trolley issupported.

Each side frame comprises :the frame mem-v bers 3 and 4 arranged end toend and abutting the trolley track 2. 5 are wheels near the outer endsof the frame members 3 and 4 and engageable with the tracks 6.

For the purpose of securing the frame members 3 and 4 to each other andclamping the trolley track therebetween and at the same timere-inforcing the frame members, the truss rod 7 is provided extendingbemath the inner ends of the frame members and having the upwardlyinclined portionsl 8 extending within 'the vtramer members andpassingthrough the abutmenfts9. Nuts 10 traine members together. j Toposition the inner ends of the frame members and also thetrolley tracktherebetween, bolts 11 extendthrough the transverse flanges 12 at'thethreadedly engagingy the outer ends of'the v rod engage the abutments toclamp the truss rod with the frame members, each Aframe member hasthedownwardly opening tunnel portion'13 'extending from near the innerend of the frame member to the abutment 9. Thetop of this tunnel portioninclines upwardly andthe abutment, asshown in Figure 1,' is formed of across wall. The f "truss rod, in assembling, is moved upwardlyl into thetunnel portions and then its ends are passed through thecross walls bymoving the frame members toward each other, after Vwhich then'uts arethreaded upon the ends of the rod.` Therouter. end portion of each framemember is'bifurcated as at 14 'forembracing the wheel 5. l

To4 strengthen the frame members, they have the' transversely extendingIiange's' 15 attheir upperedg'es and lthe web" 16 connect? ing theseflanges with the top of the tunnel portion 18 as well as the inner endianges 12. Furthermore, lthe upper ianges are continued to extendbetween the `urcations 14 to a pointnear the wheel.

The frame members 3 and 4 of the side frames are adapted to engage andclamp,

diii'erent sizes of trolley track therebetween,

depending upon the load to be carried. As shown, these side frames havethe recesses 17 in their inner lower edges which are of a size toreceive the lower flanges of the different trolley tracks, while the gheight or depth of the side members at their inner ends is such that theupper anges of the different trolley tracks extend above the` same.

The trolleyshown in Figure 5 differs from that shown in the other viewsin having the apertured abutment 18 formed by a projection in the upperface of each of the frame members 19. For re-inforcing the sides of thetunnel portion of each frame member, a

suitable cross wall 20 is provided which is adjacent to the wheel 2l atthe outer end of the :trame member.

What we claim as our invention is:

1. In a crane carriage, the combination with a pair of frame membersarranged end to end7 of means near the outer ends or" said frame membersfor supporting the same, and a common means for securing said framemembers to each other andv for reinforcing the same.

2. In a crane carriage, the combination with a pair of Jframe membersarranged end to end, of wheels near the outer ends of said frame membersfor ,supporting the same, and a truss rod for securing said framemembers to each other.

3. In a crane carriage, the combination with a pair of frame membersarranged end to end and provided with `downwardlyopening tunnelportions, of a truss rod pass ing beneath the inner ends of said framemembers and having upwardly-extending portions within said tunnelportions, and means for securing the ends of said rod to said framemembers. n

4. In a crane carriage, the combination with a pair of frame membersarranged end to end and provided with flanged inner ends and bifurcatedouter ends and intermediate downwardly opening tunnel portions, oic atruss rod passing beneath said flanged inner ends and havingupwardly-inclined portions extending through said tunnel portions, andmeans for securing the ends of said rod to said frame members.

5. In a crane carriage,kthe combination with a pair of frame membersarranged end to end and provided with downwardly opening tunnel`portions, and apertured abutments near the outer ends of said tunnelportions and above the tops of said frame members, of a truss rodpassing beneath the inner ends of said frame members and having upwardlyinclined portions extending through said tunnel portions and aperturedabutments, and nuts threadedly engaging the ends of said rod beyond saidabutments.

6. In a crane carriage, the combination with a pair of side frames eachcomprising a pair of frame-members arranged end to end, of a crossconnectionbetween said frames extending between the inner ends of Saidframe members, means for positioning the inner ends of said framemembers and said cross connection, and a common means for securing said`frame members to each lother and for reinforcing the same.

7. In a crane carriage, the combination with a pair offramemembers'arranged end to end, and a transversely extending member vbetween the adjacent ends of said frame members, of a truss'rod passingbeneath the inner ends or' said frame ymembers andengaging saidtransversely extending member and having upwardly extending portionssecured to said frame members.

8. In a crane carriage, the combination with a pair of frame membersarranged end to end, of a truss rod for'securing said :trame members toeach other and having its ends secured to said frame members abovetheirneutra-l axes and its intermediate portion engaging said frame membersbelow their neutral axes.

In testimony whereof we aiiix our signatures.
